Mayor's Message: Future Freeway-Style Interchange at Bangerter and 13400 S

By Mayor Trent Staggs

Unprecedented levels of growth throughout southwest Salt Lake County continue to drive the need for further investments into our roadway infrastructure and transportation routes. Through great intergovernmental relationships, we have been working successfully with the Utah State Legislature, the Utah Department of Transportation, and our surrounding communities to improve mobility along Bangerter Highway. With an overall goal to eliminate stoplights along Bangerter, UDOT’s traffic projections show this new freeway-style interchange system will reduce drive times in both north to south and east to west directions.

In Riverton, our projects began with the much-needed construction of a freeway-style interchange at 12600 S and Bangerter. With this project nearing completion, we look towards our second connection point at 13400 S. Having been previously funded during the 2021 state legislative session via House Bill 433, construction of the intersection at 13400 S and Bangerter is anticipated to begin as early as 2023.

Unfortunately, due to increasing inflation and limited access to materials, the costs to complete this project have increased exponentially. Currently, pricing starts at $99 million for a “Bangerter Over” option, $104 million for the “Bangerter Hybrid” option (like we have at 12600 S), and $119 million for the “Bangerter Under” option. In response to these newly established prices, I’m hopeful members of our legislature will appropriate the necessary funds needed to fully complete the project.

Part of the planning process also includes an environmental study and a public comment period that is currently in place through February 15. As always, I believe feedback from the public is key to making smart decisions that support the needs and expectations of residents. Therefore, to learn more about the Bangerter Highway project, and to provide comments or feedback on the different alignment options proposed at 13400 S, be sure to visit
